On March 14, 2026 at 17:43 UTC, a magnitude 4.5 shallow crustal earthquake struck 7 km SSW of Kolympári, Greece, at a depth of 67.5 km and coordinates 35.4846°, 23.7380°. This earthquake was detected by 34 seismic stations with moderate location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.

The epicenter is located in Greece, a region characterized by the Hellenic subduction zone, where the African Plate subducts northward beneath the Aegean at roughly 35 mm per year. The nearest mapped fault system is the Hellenic Trench. View all earthquakes in Greece.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.5 earthquakes can continue for several days and gradually diminish over time.

Has Greece had earthquakes this big before?

The largest recorded earthquake in Greece was the M8.5 Crete earthquake of June 29, 1303. Today's magnitude 4.5 event is significantly smaller than that historical record.

What should I do after an earthquake?

If you were in the affected area: check yourself and others for injuries, inspect your home for damage, and be prepared for aftershocks. For detailed guidance, see our earthquake safety guide and emergency planning resources.
